PP

actually the interalia spec say 20 vdc min, 19 will work

thanks... the interalia tech I called told me 24... I'm thinking 19 if fine also... I just don't know what the heck is wrong... I out my route and trunk and rebuild them. I can dial the RAN via the ACOD from my phone without any problem... but after a minute or so it ERR220's out and then I can't access it... I get a fast busy intercept. When I to a RAN c r Test in LD 32 I get err trk041 - "The RAN, MUS or AWK device specified for customer c and route r is not
operable." -

I just don't know...

Make sure the trunk type is AUD for audichron recording device. I would also check the dip switch settings on the interalia. What is your starting arrangement on the trunk route? It should delay until the start of the message.

Hello, Here is what I have found to be my experience,

The 24VDC is what should be present on the CP (3rd) lead of the Trunk Card, this voltage should be present even with the Interalia disconnected. If you have the Interalia configured in the Continuous Play (CP-NO) mode the announcer is designed to short that voltage to ground (this is why the grounding is so important) every time the message starts over. This signal (short) is what "tells" the PBX that the Interalia is about to play the message and a caller waiting for that message should be connected at that point. If the PBX does not see this short in a certain period of time it errors out the port (Error 220)

A way of verifying if the Interalia is operating properly is to:
1) Monitor this voltage - The CP leads of the Interalia should momentarily close (for 250ms) at the start of the recorded message. If, for example, the message was ten seconds long you should see the voltage drop every ten seconds.
2) You could also verify the Interalia's operation with the PBX out of the picture - Connect your meter across the CP leads of the Interalia, the CP leads should provide a momentary closure (short) every time the message is about to start (again, every ten seconds).

Ultimately (once you verify the operation of the Interalia), the questions is how much voltage should be present on the CP lead of the trunk card? My experience has been that there should be almost 24VDC.

The 20 VDC Min that PP is referring to is when a PBX is configured for E&M signaling and the Interalia is triggered to play a greeting. In this case the Interalia would also need to be configured for E&M signaling (either Pulse or Level Start) - Applying 20 VDC Min to the Start Leads of the Interalia will activate the announcement in the Interalia.

How long is the message on the Interalia? I found something on the Nortel website that says the Audicron interface requires a CP every 64 seconds. If it doesn't hear it, the ERR220 is generated.

Also, another note says someone had a problem when the Interalia ground wasn't the same as the system ground.

Thanks all for the replies... I am set up as AUD, DDL, CP and the message length is under 10 seconds for testing purposes...

Interaliatech,
I've monitored the message with my test set and verified that the voltage does drop during the short. I did this by putting on meter lead on the cp lead org/wht and the other to ground... Now "to ground" is what I'm worried about... I've tried it using the ground lead Grn/Wht, I tried grounding to a BellSouth 21x ground bus, to the main breaker box and I even took cross connect wire to the base of the pedestal where the switch is grounded and the result is the same... I've tested from the Grn/Whit to the breaker box cabinet and read 5 ohms which I believe is a standard for a good ground... nothing changes...

The voltage, 19 vdc, is the same on different cards and IPE shelves... I'm using a NT8d14 BB card... is this and XUT or the updated EXUT card?

You stated,
"You could also verify the Interalia's operation with the PBX out of the picture - Connect your meter across the CP leads of the Interalia, the CP leads should provide a momentary closure (short) every time the message is about to start (again, every ten seconds)." When you say, connect your meter across the CP LEADS, what do you mean? Each channel has one CP lead and one GND. The GND is looped to the other channels... So when you say "across" the CP leads... ???

my dip switch settings have not change... they are off off off (123) on on off on (4567) which is continuous play. Attached is my RDB and Trunk. I need to know if I'm using an XUT or EXUT card... I think EXUT... The TIMP is different for each. Just found out that XUT only supports continuous play... I have a vintage BB which is what interalia calls for so I relatively sure I have an EXUT card.

I also get this when I test the RAN Route...
TRK0041 c r
"The RAN, MUS or AWK device specified for customer c and route r is not
operable."
Severity: Minor

I think the problem is my switch is not seeing the short to ground... I see it at the CP lead... That's why it will work for about a minute then time out with the err 220... the switch never sees all the shorts within that minute. The question is, why is my switch not seeing the short!?

Sounds like too much resistance on the ground. The Ohms should be less than .5.

Can you try this: Disconnect the XUT CP lead from the Interalia, then run a wire connected to the system ground. Touch this to the CP lead on the MDF during the RAN playback and see if the system connects the call to the RAN (instead of letting the Interalia attempt to close the CP lead to ground). This would at least let you know if you have a wiring problem between the MDF and the Interalia.
